Abstract (en)

[origin: EP1030168A1] Signal-processing circuit comprises a pre-amplifier (1) and an analogue to digital converter (2) arranged serially after the pre- amplifier. The pre-amplifier works as a differential pre-amplifier with differential input and output and high pass (3,4) inputs. The pre-amplifier works to suppress any equal phase non-measurement signals and any low frequency signals.
